JOURNAL-BOX ATTACHMENT.

Application filed @ctober 27, 1922.

(iii whom him may 0011007 n. Be it known that i (Pris T. Genus, a :itizen of the United ates, residing at New Jersey, have invented a Journal-Box Attachment, or which the following? is a specification.

' diireren iauufacturers lantations ith cars and noes, and the various appliances arts thereof: have become more or less irizcd as to dimensions. Consequently lantation can order of any such manu- "acturer a stoclcpart which will fit the tandardized appliance on hand. Among ther such standardized devices may be Voted a journal-box adapted to carry a bearng-bloclr having at its outer end an upurned square flange which fits into a squared recess in the outer part of the jourrial-box, said journal-box and bearingblock being designed to receive a car-axle having a collar around its end. Said bear- 'n..j-block ained in the journal-box by unnsverso s ,mmetrical pin passed through 1e i303; in front of the squared flange aforeaid, and located at a standard distance hove the axle and its collar. In the course of: service, the bearing-block becomes worn thin so that ultimately said axle-collar will come into contact with said retaining-pin and wear it away.

The object of the present invention is to provide an improved block-retaining pin which. without interfering with the standardized dimensions aforesaid, will not be worn away by the axle-collar.

The invention consists broadly of a non symmetrical retainingpin of approximately-uniform and unreduced cross-section thr uchout its length and bowed upwardly in the middle. The invention will be best understood. by reference to the accompanying; drawi s, which illustratea preferred embodiment thereof, and in which:

Fi I is a vertical section taken longitudinally through the journal-box and bearingblock and axle-end. and showing one of the holes for the new retaining-pin; and

Fig. 11 is an end view of the same, with the box-cover removed, showing said new retaining-pin in position.

in these drawings 3 indicates a portion of he journal-box. e. is the bearing-block lothiwin, and having: at outer end Serial No. 597,248.

the upturned squared flange 5 fitted into a squared recess in said journal-box. 6 is the outer portion of the axle, having around its end the collar 7. 8 is the new retaining-pin, a headed pin whose middle is bowed upwardly, as at 9, substantially concentric with respect to the axle and its collar, said pin being retained as by a cotter-pin. Said upwardly-bowed pin is of approximately-uniform and unreduced cross-section throughout its extent, instead t being a straight pin weakened by reduction of material along its lower face.

Preferably said bowed pin 8 and the holes therefor are non-symmetrical. Otherwise a careless workman might insert the pin with its bow downward, almost in contact with the axle-collar when first installed. There fore, the tw holes in the boX and the pin itself are formed non-symmetrical, in the present instance being shown as semi-cylindrical, although any other non-cylindrical and unsymmetrical form maybe employed, to insure that the pin can only be inserted with its bow upward.

The invention is not limited to the precise structure and arrangement herein shown; and parts of the invention may be employed to the exclusion of other parts, without departing from the broad spirit of the invention.

T he invention having thus been described, what is claimed is:

1. The combination of an axle having around its end a collar, a bearing-block therefor terminating short of said collar and having at its outer end an upturned flange, a journal-box for receiving said bearing-block and axle, said box being provided at each side with a non-symmetrical hole located beyond the outer face of said flange and in the vertical plane through said collar. and an upwardly-bowed retainingpin of uniform and unreduced but non-sync metrical cross-section throughout its length and fitted to enter said holes and lie in said vertical plane.

2. The combination of an axle having around its end 'a collar, a bearing-block therefor terminating short of said collar and having at its outer end an upturned flange, a journal-box for receiving the same and provided with two registering semicylindrical holes located beyond the outer face of said. flange and the vertical plane All the tore' oins is old.

' vertical plane.

t. The combination of a hearing-block, a journal-box into which said block is fitted. and an upwardly-bowed retaining-pin of ijiniform and unreduced but non-symmetrical cross-section throughout its length and fitted into oorrespondingly-shaped holes' in said boX and bearing against the outer end of said block.

5.,The combination of a bearinghlocl a journal-box into which said block is fitted, and an upwardly-bowed retaining pin fitted into holes' in said box and bearing against the outer end oi said block, said pin being of uniform and unreduced (FOSS-SSCtlOD 30 throughout its length.
